6 Meter Feedline?

[Once Bitten]

What coax should I use for 6 Meters?

 

[Mudfoot]

How long will your run be?

 

[mr_fx]

if it's a short run I would just use rg8x (mini)

 

[binrat]

RG-8, LMR 400, LDF-4.

 

[W5LZ]

Or from the other end of that sort of question... what kind of coax do you have?

Make that a very, very short run. Six meters is about the point where things start to take a turn as to what to use for feedlines. Without a doubt, use the very best and lowest loss feedline you can afford. On 6m RG-58 has almost 4 dB loss per 100 feet while Belden 9913 has just 1 db per 100 feet. I use Andrew LDF4-50 which has a bit less than 0.5 dB loss per 100 feet. It's not cheap but I need about 160 feet to reach the antenna so loss is a factor due to length for me.

by short I mean less than 20 feet (maybe less than 10 really)

Maybe 75 feet. Less than 100 feet.

Nothing yet for the 6 meter antenna.
CSH-A505S on 40 foot mast.

Sound like LMR 400 will be it.

Good choice, try to get the real deal cable. If it doesn't say Times Microwave, your buying iffy copycat cable.

I would go with LMR 600 or half inch Heliax if the run is 100' or more. It is desirable to keep line losses below 1 db on 6 meters and above, if possible.

It definitely will be less than 100', but probably more than 75'.
